The five most important technologies in the field of paper packaging and printing

Offset online cold stamping technology, web gilding technology, fixed-length stretched composite printing evasion laser slit technology, laser pattern embossing transfer technology and combined printing technology are the five most important technologies in the field of paper packaging and printing.

1. Offset online cold stamping technology

Traditional hot stamping requires a special metal hot stamping plate. The hot stamping material is transferred to the surface of the printing material by means of heating and pressing. The speed is relatively slow, and it is difficult to add hot stamping with offset printing. Offset online cold-stencil technology is to paste the graphics and images that need to be stamped on the surface of the substrate through the adhesive under normal temperature conditions. The way to achieve this is to directly use the two units of the original offset press, a set of printing adhesive layers, and a set of transfer metal hot stamping foils.

Advantages: hot stamping speed, high efficiency; a paper-driven printing and metal foil transfer digital printing, high registration accuracy; cold hot plate resolution can reach the resolution of offset printing plate, can be hot stamping fine graphics At room temperature, without heating, it can be hot stamped on the surface of temperature-sensitive materials; save energy.

2, web bronzing technology

Web-foil stamping machines have taken the lead in getting mature applications in China's cigarette package market. With the increase in demand for high-efficiency, high-quality stamping jobs, the web stamping machine will also achieve greater development. At present, the relatively mature enterprises include: Changde Jinpeng Printing Co., Ltd., Yunnan Qiaotong Packaging & Printing Co., Ltd., Yunnan Yuxi Printing Co., Ltd., Chongqing Hongsheng Printing Co., Ltd., Yunnan Jiuji Color Printing Co., Ltd., and Dongguan Zhiyuan Color Printing Co., Ltd. Company etc. Frequently encountered enterprises with large batches, high gilding process requirements, and short customer delivery schedules can focus on web bronzing technology.

3. Fixed-length stretched composite printing avoidance laser slit technology

Laser holographic laser transfer paper is a new type of packaging material used more and more widely in the packaging and printing industry at home and abroad. However, a major problem is that when printing on a rotary gravure printing machine, a laser version of the RIP seam is easily generated, resulting in great waste. At present, there are mainly two kinds of fixed-length and stretched composite printing and avoiding the laser seam technology solutions for connection and offline.

Packaging and printing companies can make reasonable choices based on their own funds and actual production conditions. If the company has rotogravure equipment, you can use an off-line solution to emboss the bumps. Buy from the composite paper manufacturer laser-aluminized transfer paper that is capable of avoidance seams, and only need to modify the feed mechanism of the original rotary printing equipment. Yes, the investment risks and technical risks of the company are relatively small.

Laser pattern embossing transfer technology is a high and new technology integrating decoration, anti-counterfeiting and environmental protection. Its outstanding advantages are: meeting environmental protection requirements, anti-counterfeit effects, and reducing production costs.

5. Combination printing technology

In a sense, a combination printer is no longer simply a printing device, but a streamlined production line that integrates multiple types of printing and postpress processing.

Combination printing is a combination of various printing process technologies, ie integrating multiple printing methods (such as flexo, offset, gravure, screen printing, and even digital printing) and post-printing processes on the same production line ( Such as light, film, die-cutting, indentation, hot stamping, embossing, etc.) combine the advantages of various printing and post-press processing methods to achieve the best printing effect.
